TEMPORARY BINDER OR LOOSE-SHEET HOLDER.

' Specification of Letters Patent.

Patented June 9, 1908.

App ication filed July 31, 1905. Serial No. 272,033.

T 0 all "whom it may concern:

Be it known that I, HARRY F. Bnsnoxe, a citizen of the United States, residing at Kalamazoov in the county of Kalamazoo, State of lllichigan, have invented certain new and useful Improvements in Tern orary Binders or Loose-Sheet Holders, of w 'ch the following is a specification.

This invention relates to improvements in temporary binders or loose sheet holders.

It is articularly adapted to the style of binder i lustrated and described in my application for Letters Patent filed August 5, 1004, Serial Number 219,624, and is a modification and in some respects an improvement on that structure, although it is applicable foruse in other relations.

The objects of this invention are, first, to 'rovide an im roved temporary binder or oose sheet hold iir which may be very quickly and easily adjusted to receive or remove one or more sheets, as desired. Second, to provide an improved temporary hinder or loose .sheet holder adapted to securely retain any number of sheets or. leaves, from one to its maximum capacity, whiclrmay be quickly adjusted to receive or to permit the removal of any number of sheets or leaves.

Further objects, and objects relatin to structural details,-will definitely appear om the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. I

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is fully illustrated in the accomanying drawing forming a part of this specication,-in which:

Figure 1 is-a plan view iromthe rear or outside ofm improved temporary binder or loose sheet older in its open position, the rear walls of the cover-being removed. Fig. 2 is an enlarged detail. transverse sectional view-taken on a line corresponding to line 2 2 of Fig. 1 showing structural details of the adjusting mechanism. Fig. 3 is anenlarged detail view taken online 3 3 of Fig. 2. Fig. 4 is an enlargarl'detail view taken on a line corres ondi to line 4 4 of Fig. 1.

' n the drawm the sectional views are .aaken looking in t c direction of the little arrows at the ends of the-section lines and mum lar letters of reference reter to similar parts throughout the several views. Referring to the drawing, the covers A A are formed with chambers therein to receive the adjusting mechanism of the binder. A

pair of clamping bars F are pivotaliy secured to the covers by suitable hinges, as f; These bars are preferably of the form described in my co pending application heretofore referred to. Binding cords C are arranged throu h the bars and are secured at one end to t e cross-bar B. The binding cords are r'eferably formed of a single piece, which is ooped; about the blocka at the mnerend of the cover A. This block is )rer'erably curved,

so that the binding cord reely adjusts itself .70 over it, thereby maintaining an equal tension upon the cord and clamping bars throughout their length.

The bar B is adjusted by means of the iongitudinally arranged threaded shaft D, which 76 is supported in suitable bearings d within the cover A. This shaft is controlled by a suit able key, as d. The bar is connected to the shaft by means of the'threaded half-nut or block b which is adjustably secured to the 80 bar. (See Figs. 2 and 3.) The threaded block b is held into engagement with the screw shaft by the cam c, which is slidably mounted upon the rockshaft E. The cam e is arranged in a suitable slot in the bar B, so n that as the bar is shifted the cam iscarried back and forth upon the rockshaft. The rockshaft is preferably rectangular in crosssection, to engage the dam.

finger piece or lever E for manipulating the rockshaft E, is arranged throng a-suitable opening a in the cover wall A. B manipulating the rockshaft the cam 0' 1s fihrown into or out of .engagementwith the lock b, causing it to engage'or release'the shaft, thereby connecting or disconnecting the bar B thereto.

, When it is desired to open the binder, the lever E is mani ulated to release the block from the shaft, til allowing the clamping bars to be drawn 11 art against the tension of the springs B" w ch are-secured to the bar B. In closing the clam mg means, the sprin B retract the .bar to take up the slao in the binding 105' cords. The lever E is then manipulated to throw the block into engagement with the screw, and by means of: the

ev the-clamping ereby freeing the bar Band on account of its structura bars are drawn tight upon the leaves. In order to enable the use of longer return springs than would otherwise be practical, t 1e bar B is providedwith inwardly projecting arms B, to which the springs are attached, as clearly appears in 1.

By arranging the parts as I have illustrated and described, 1 am enabled to clamp the leaves very securely and at the same time I provide a means by which the clamping means may be quickly and easily adjusted for removing or inserting sheets.

I have illustrated and describerLmy imroved temporary binder or loose sheet iolder in detail in the form lpreferred by me simplicity and convenience in operation. I am,- however, aware that it is capable of considerable variation in structural details without departing from my invention.
